Study Notes

ARC 142: Building Utilities - Plumbing and Sanitary System

Course is about plumbing and sanitary systems in buildings
Prepared by AR. J.I.S.B.

Plumbing - Introduction

Plumbing is the art and technique of installing pipes, fixtures, and other apparatuses in buildings to bring in and remove liquids, substances, and ingredients
Plumbing originates from the Latin word "plumbum" meaning lead, as lead was once a common material for pipes
Plumbing refers to a system of pipes and fixtures installed in a building to distribute potable water and remove waterborne wastes

Plumbing - History

Plumbing profession originated in the Philippines in the 17th century, established by the Spaniards
In 1902, the plumbing trade was recognized by the government
Master Plumber John F. Hass was the first Chief of Division of Plumbing Construction (1898-1946), with the plumbing code based on the US plumbing code incorporated into the Building Code of Manila
In 1935, the National Master Plumbers Association of the Philippines (NAMPAP) was established
City Ordinance 2411, known as the Plumbing Code for the City of Manila, enacted
Republic Act No. 1378, the Plumbing Code of the Philippines, was approved in 1954
The Revised Plumbing Code of 1999 was enacted in 1999 by President Joseph Ejercito Estrada

Plumbing System - Fundamentals

The plumbing cycle encompasses supply, distribution, use, collection, and disposal
- Supply: Water from lakes, rivers, or reservoirs through water mains and storage tanks
- Distribution: Water distribution through pressure piping networks
- Use: Plumbing fixtures in the building
- Collection: Wastewater collected through gravity and pipes
- Disposal: Wastewater treatment and disposal through sanitary and storm sewers (to treatment plants)
Plumbing objectives:
- Supply water to various building parts
- Remove human waste and other substances
Water Supply requirements: adequate water for fixtures & prevent backflow of used water
Drainage System requirements: fast waste removal with minimal leakage, prevent vermin/noxious gases

Plumbing System Components

Water Supply and Distribution System
Sanitary Drainage and Disposal System
Storm Drainage System
Plumbing Fixtures
Fire Protection System
Fuel and Gas Piping System

Common Plumbing Terms

Bleed: Releasing excess air in a pipe using a valve.
Brass: Corrosion-resistant material often used in pipe fittings
Branch Drain: Fixture drain connected to the main drain pipeline
Soil Pipe: Pipe that carries waste from a toilet

Plumbing System - Additional Terms

Effluent: Liquid waste in a septic system
Fitting: Part connecting two pipe sections
Flow Rate: Amount of water flowing through a system (measured in GPM or GPH)
Gallons per flush (GPF): Measurement of water needed to flush a toilet
Gray Water: Wastewater from non-toilet fixtures
Kilopascal (kPa): Metric unit of pressure (1/100th of an atmosphere)
Maximum Containment Level (MCL): Maximum contaminant amount permitted in water supply
Non-Ferrous Metals: Metals without iron, non-reactive, often used in plumbing
Potable: Consumable water that is safe to drink
Pressure Head: Unit of measure for pressure caused by water depth (one foot's depth is one pressure head)
Riser: Vertical water pipes connecting to fixtures
Sediment: Debris in water tanks
Soil Pipe: Pipes that transport wastewater from fixtures
Trap Seal: Water seal in a plumbing trap (prevents drainage gases)
Trap Weir: Highest point of water in a P-trap or S-trap
Water Hammer: Loud banging sound due to sudden shutoff of water supply

Plumbing Tools and Materials

ABS: Acrylonitrile Butadiene Styrene (plastic pipe)
Auger: Tool used to clear clogs from drains
Blow Bag: Tool used to force water through clogs
CPVC: Chlorinated Polyvinyl Chloride (pipe)
Dope: Lubricant used on pipe threads
Polybutylene (PB): Bendable tubing
Polyethylene (PE): Flexible pipes
PEX: Crossed-linked polyethylene tubing (stronger than PE)
Plumber's Putty: Dough-like substance to seal joints
Plunger: Tool used to unclog drains
PVC: Polyvinyl Chloride (plastic pipe)
Snake: Thin, flexible cord to remove clogs from drains
Teflon Tape: Non-stick tape for pipe joints

Septic System-Specific Components

Absorption Field: Area to filter and disperse wastewater from septic tanks
Leach Line: Pipes carrying wastewater to the absorption field
Septic Tank: Underground tank for wastewater temporary storage
